Tests failing. Unknown Attribute

My tests (that previously worked) are now failing. I am getting the same error for all tests, which is as follows:

Failure/Error: let!(:todo_list) { TodoList.create(title: "Grocery list", description: "Groceries") } ActiveRecord::UnknownAttributeError: unknown attribute: description

I have copied over much of the code from the downloadable project files, so I'm not sure why I am getting this.

Check your schema.rb file and see if your todo_list table has this attribute.

Okay, I think that is the issue, but i'm not sure how to fix it. Currently my schema.rb todo_list table is showing descriptions (plural) rather than description. It looks as though I need to change this through the console rather than directly in Sublime Text (since every time I run a migration, it changes back to descriptions (plural).

On a separate note, I notice that the next video on adding a complete_at timestamp produces a line for this in the schema.rb file of the downloadable project files. However, this is not showing on mine. I have gone through the video about 3 times and feel as though I have done every step...but i suppose I'm missing something. Thanks for the help.

Okay, I believe I fixed it for the most part. I changed the schema.rb file to show description (singular instead of plural). Then ran rake db:schema:load. Everything seems to work for the most part now.
